Ville Syrjälä 848496e590 drm/i915: Wait up to 3ms for the pcu to ack the cdclk change request on SKL ... Bspec tells us to keep bashing the PCU for up to 3ms when trying to inform it about an upcoming change in the cdclk frequency. Currently we only keep at it for 15*10usec (+ whatever delays gets added by the sandybridge_pcode_read() itself). Let's change the limit to 3ms. I decided to keep 10 usec delay per iteration for now, even though the spec doesn't really tell us to do that.
